The billionaire Winklevoss twins who sued Mark Zuckerberg over the creation of Facebook are considering a UK base for their cryptocurrency giant, decrying a “hostile” climate in the US.

Cameron and Tyler Winklevoss said that they were thinking about setting up a “second headquarters” for the crypto exchange Gemini in London.

The brothers this week met officials at the Financial Conduct Authority (FCA) and Bank of England as they scout locations to focus Gemini’s investment.

US cryptocurrency companies are complaining of an increasingly difficult regulatory environment following the collapse of FTX, the bankrupt exchange run by Sam Bankman-Fried.
